氨酰-tRNA的单个模块的可变性知之甚少,尽管与进化、翻译准确性和非天然氨基酸的掺入相关。在这里,我们剖析了连续变化的影响,在四个领域的Ala-tRNA 3Ala在一个纯化的系统翻译。为了揭示对肽产物产率的主要影响,需要分离五种氨基酸,而不是一种。省略tRNA修饰几乎没有影响,但反密码子突变非常抑制。令人惊讶的是,改变终端CCA的CdCA有时是抑制性的,非同源氨基酸有时是补偿性的。结果对翻译保真度和工程有影响。
The changeabilities of individual modules of aminoacyl-tRNAs are poorly understood, despite the relevance for evolution, translational accuracy and incorporation of unnatural amino acids. Here, we dissect the effect of successive changes in four domains of Ala-tRNA3Ala on translation in a purified system. Incorporating five amino acids, not one, was necessary to reveal major effects on yields of peptide products. Omitting tRNA modifications had little affect, but anticodon mutations were very inhibitory. Surprisingly, changing the terminal CCA to CdCA was sometimes inhibitory and non-cognate amino acids were sometimes compensatory. Results have implications for translational fidelity and engineering.
